I have found that very valuable wetting preparations which possess a great efficacy when used in mercerizing lyes can be prepared by mixing phenols, like phenol, cresols, xylenols and others, with such derivatives of polyhydric aliphatic alcohols that contain at least one free hydroxyl group and at least one ROR group, wherein R and R represent alkyl, aralkyl, aryl, alkylidene, aralkylidene, alkylene, aralkylene and arylene groups. Such compounds are for instance the mono-(alkyL, aralkyl-, aryl-) ethers of glycol and of polylethylene glycols, the. polyethyleneglycols t alkylethers and the acetals of g1 cerine.

When added to alkaline lyes, t ese mixtures impart to them very durable wetting-out properties, which are not affected by the temperatures generally used in mercerizing processes. In order to obtain the desired effect, the above described mixtures are added in suitable quantities to the alkaline lyes of various concentrations or the mixtures are generated therein by adding their constituents under good stirring.

According to the present invention it is possible to mercerize dry raw sized cotton' bres very rapidly and to obtain a very high lustre in a single treatment. 1

The following examples, 7 without being limitative, illustrate the new process, the parts being by weight.

Example To 100 parts of a caustic soda solution of 38 B6. are added under good stirring 0,94 parts of phenol and thereafter 0,17 parts of diethyleneglycolmonoethylether, stirring be ingcontinued until the solution becomes completely homogeneous. The thus obtained alkali lye is ready to be used for r'nercerizing whereby it wets out immediately raw sized cotton fabrics and'allowsto obtain a level mercerization in a-very short time.

Example 2 To a mercerizing lye of 35 B. are added 1,14 per cent. of a mixture consisting of 98 per cent. of a technical cresol mixture and 2 per cent. of technical diethylene glycolemselves, monoand d1 monobutylether. The wetting-out action of 4 Example 3 To 100 parts of a caustic soda solution of 30 B. are added 1,5 parts of a mixture consisting of 85 per cent. of a technical xylenol mixture and of 15 per cent. of a mixture of the monoxylenylglycerine isomers. The thus obtained clear solution immediately wets out raw sized cotton material.

Example .4 To 100 parts of a caustic soda solution of 32 B. are added 1,17 parts of a mixture T0100 parts of a caustic soda solution of 32 B. and at a temperature of 35 C. are added 1,17 parts of a mixture composed of 80 per cent of technical xylenols and of 20 per cent of acetoneglycerine of the formula i Hz-JJH-OHr-OH v The thus obtained alkali lye possesses very good wetting-out properties for raw sized cotton yarns and fabrics.
